近年来，研磨系统和研磨剂取得了重大进展。为了实现这些系统的最大潜力，还必须对选矿操作进行改进，以实现系统的整体改进。本文论述了采用反向电镀法的旋转式金刚石修整辊的开发、制造工艺和优点。文章还讨论了聚晶金刚石的发展，以及这两种技术的结合如何为当今行业提供最先进的修整工具。

IN RECENT YEARS, MAJOR ADVANCEMENTS HAVE BEEN MADE IN GRINDING SYSTEMS AND IN ABRASIVES. TO ACHIEVE THE MAXIMUM POTENTIAL OF THESE SYSTEMS, IMPROVEMENT ALSO MUST BE MADE IN THE DRESSING OPERATION FOR A TOTAL SYSTEM IMPROVEMENT. THIS PAPER ADDRESSES THE DEVELOPMENT, MANUFACTURING PROCESS, AND BENEFITS OF ROTARY DIAMOND DRESSING ROLLS UTILIZING THE REVERSE PLATED METHOD. IT ALSO DISCUSSES THE DEVELOPMENT OF POLYCRYSTALLINE DIAMOND AND HOW THE INCORPORATION OF THESE TWO TECHNOLOGIES PROVIDES THE MOST TECHNOLOGICALLY ADVANCED DRESSING TOOL AVAILABLE TO INDUSTRY TODAY.
